Projector as second monitor issue

[Bbarton]

Hi!

I am setting up an HDMI projector as a second monitor to run my LOR music as mp4s with video.  I have gone into sequence info and changed the video default to go to full screen on my second display.  However, when I load up the show using the scheduler, only the first video will play as full screen; any subsequent files will play with the screen minimized in the lower left-hand corner with a smaller white box just below it.  I have also tried inserting a regular song (mp3) in between the two mp4 files in case it was an issue with resetting the display, but that did not make any difference.  

I am not sure if it is a software issue, hardware issue or just a Windows10 second-monitor problem.  Has anyone had any similar issues with it? 

Any advice would be greatly appreciated!

Thanks,

Beth
